This set contains a pair of accurate resin main wheel hubs designed to fit Barracuda Studios resin tires, for those not building the Tamiya P-51 kit. For modelers building a P-51A, P-51B, P-51C, P-51D or P-51K from Hasegawa, Trumpeter, Dragon, Hobbycraft or Monogram and using resin tires/tyres BR32029, BR32030, BR32031, BR32032. These hubs are not intended for the Tamiya kit, as the mounting to the gearleg is different.
